Product Description

Product Description

Discover the cutting-edge brilliance of our White Silicon Dioxide Precipitated Silica, a marvel produced through the meticulous wet chemical precipitation method. This synthetic amorphous silica (SiO2) stands apart with its creation via a low-energy, eco-friendly water treatment process, seamlessly blending sodium silicate and mineral acids. The result? A superlative, porous material boasting a high surface area, with customizable particle size and morphology, perfectly tailored for diverse applications. Revered for its unparalleled reinforcing, thickening, and matting properties, this silica is a cornerstone in the rubber, plastic, and specialty chemical industries. It revolutionizes the rubber industry, serving as a superior alternative for tire treads to carbon black-driving down rolling resistance-and as a key component in shoe sole materials. Beyond that, this silica shines in personal care products, enhancing toothpaste abrasives and acting as a matting agent in paints. In the food and feed sectors, it excels as an anti-caking agent, streamlining the flow in powdered foods, and as a reliable carrier. Its versatility extends to agriculture, where it is an effective slow-release pesticide carrier, empowering sustainable farming practices.
